Tuesday’s weather

Say goodbye to the 90s, and hello to the 70s and low 80s. After unseasonably hot weather on Sunday and Monday, much cooler weather will settle into northern Colorado in the wake of a cold front. Temperatures will be slightly warmer-than-normal, even for late summer, with highs in the upper 70s to low 80s Tuesday afternoon. Skies will be mostly sunny.

Fall arrives Wednesday evening, and more seasonable weather will usher in the new season. Afternoon temperatures will be in the upper 70s to low 80s for the rest of the week. Morning lows will be in the 40s. Scattered thunderstorms will be possible on Wednesday, but otherwise the extended forecast looks dry.
